Certify your Digital Contents on the Ethereum Blockchain

Certifying digital contents is now easier than ever!

Certy is the application that allows you to certify Digital Contents of any extension on the Ethereum Blockchain.
You can create an immutable record by notarising pdf, images, projects, music, video etc
in a tamperproof way on the Blockchain.

After notifying your Digital Contents, Certy will issue a Certificate that represents
the immutable record stored in the database managed by smart
contract that ensures the successful certification with these details:

-Encripted fingerprint of your Original Digital Content
-Your Identity as Certifier of the Original Digital Content
-Memo label for the Digital Content
-Hash of the related transaction to certify the Original Digital Content by Smart Contract
-Timestamp of Certification of the Original Digital Content

Then, again through Smart Contract, Certy allows the User to easily and automaticallycheck the compliance of a Content with the Certified Original.
Just entering the public key of the Certifier wallet and the content to verify.
Certy automatically makes the comparison of the fingerprint on the database managedon Blockchain by the Smart Contract and returns the result,
this verification is fully automated and not manually as other similar applications do.

Certy also provides to the Certifier the complete list of the Original Digital Contents
notarized till now with all the data
